Answer: 24 drops
Step-by-step explanation:
Given : To paint a sunset, we make a shade of orange paint using 5 drops of red paint for every 8 drops of yellow paint.
⇒ The drops of red paint is proportional to the drops of yellow paint to paint a sunset.
If we use 15 drops of red paint therefore by direct proportion we get,
[tex]\frac{8}{5}=\frac{x}{15}\\\Rightarrow\ x=\frac{8}{5}\times15\\\Rightarrow\ x=8\times3=24[/tex], where x is the number of drops of yellow paint.
Thus we need 24 drops of yellow paint.
